Fillings are used to repair damaged teeth and restore their function and appearance. However, sometimes fillings can become damaged or fall out, allowing new decay to form and causing the tooth to turn black. This guide aims to explain why fillings can turn black and what you can do to address this issue.
[Fillings Overview]
Fillings are typically made of silver amalgam, composite resin, glass ionomer cement, or porcelain. They are placed in the mouth to fill in cavities orrepair broken teeth and are an essential part of maintaining good oral health.
[Why Do Fillings Turn Black?]
There are several reasons why fillings can turn black:
- Oxidation: The metals in amalgam can oxidize and turn black.氧化是牙齿填充物变黑的自然过程，随着时间的推移会变得明显。
- Wear and Tear: As the edges of the filling wear down, the metals become exposed and can oxidize and turn black more readily.磨损和擦伤经常会导致填充物边缘暴露。
- Leakage: If gaps form between the filling and the tooth, fluids can seep underneath the filling and cause oxidation and discoloration.这种泄露可以指示填充物与牙齿结构的粘合逐渐减弱。
- Galvanic Shock: When two dissimilar metals touch, like amalgam and gold crowns, galvanic shock can corrode the metals and turn the filling black or dark grey。当两种不同的金属接触时，比如汞合金和金冠，会引起腐蚀。
- Dietary Stains: 酸性或染色的食物和饮料（如咖啡、茶或浆果）可能会使腐蚀的边缘变色。定期口腔清洁可以最小化这种类型的染色。
[What Can You Do About a Black-Filled Tooth?]
- Replace the Filling: If the filling has a worn-out look or exposed metal, it may be time to replace it with a new one. This can prevent further decay from forming.
- Seek Professional Help: 如果填充物掉落并且看起来有严重的损坏，请立即联系牙医进行评估和治疗。牙医将检查牙齿以确定最合适的治疗方法。
- Prevent Future Issues: 保持良好的口腔卫生习惯，如定期刷牙、使用牙线和用漱口水清洁，可以帮助预防未来填充物的问题。
- Talk to Your Dentist: 如果您担心填充物的颜色变化或其他口腔健康问题，请咨询牙医。他们可以提供个性化的建议和治疗方案。
